Orangutan Escape: Short-Circuits Wires, Builds Ladder To Flee Zoo In AdelaideKarta, a 27-year-old orangutan short-circuited electrical wires and built a make-shift ladder to climb a fence in an escape attempt at Australia’s Adelaide Zoo on Mother’s Day, causing the zoo’s evacuation on one of its busiest days.

The Independent reports:

Karta, a 27-year-old female, jammed a stick into wires connected to the barrier, then piled up shrubs, roots and debris to create a platform. Using it as a stepladder, she climbed up onto the concrete and glass wall surrounding her enclosure, where she was spotted by a member of the public who raised the alarm.

After escaping its enclosure but not quite making it out to the public, fifteen zoo employees responded and returned Karta.
